The radius of a circle represents the distance between the center and the boundary of the circle (circumference). The radius is generally denoted by “R” or “r.”. The word “radius” is the singular form, while “radii” is the plural form.
Radius, Diameter and Circumference. The Radius is the distance from the center outwards. The Diameter goes straight across the circle, through the center. The Circumference is the distance once around the circle. And here is the really cool thing:
The Radius of a Circle: A radius is a line segment with one endpoint at the center of the circle and the other endpoint on the circle. Radius = $\frac{Diameter}{2}$ Diameter of a Circle: A line segment passing through the center of a circle, and having its endpoints on the circle, is called the diameter of the circle. Diameter = 2 × radius

3 sie 2023 · The radius of a circle is the distance from the center of the circle to any point on its circumference. It is half the length of the diameter of the circle. Shown below is the radius of the circle.
The radius of a circle is one-half the length of its diameter. The two radii of length r, shown above for the circle, lie on its diameter, d. This means that d = 2r or . Central angles. A central angle is formed by two radii of a circle. Sides OA and OB of central angle AOB are formed by radius OA and radius OB. Radius of a polygon.
